JEROME VAUGHN, OFDOWNIEVIIJLE, CALIFORNIA.

Letters Patent N 99,980, dated Febr-nary 15, 187 0.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom. 'it may concern:

Be itknown that I, JEROME A.VAUGHN, of Downieville, county ofbierra, State oi'Galiiin-nin, have invented without iilrther invention or experiment.v

The object of my invention is to construct an improved horizontal windmill in which the valles are allternately opened and closedhy the action ofthe wind as they turn, the t-wo on opposite sides hcingconnected' by rods extending across within the trame.

To' more fully explain my invention, reference is made. to the accompanying drawings forming a part of this specification, ot' which- Figure 1 is a side sectional elevation;

Figure 2 .is a plan.

A1A are the two rims lying in parallel horizontal planes, and connected together by vert-ical posts or slats B, the distance between the riinsbeing equal to the proposed width of the vane-s.

These vanes C C may be solid, or they may he oom posed of frames covered with canvas or equivalent material, as here s hown, and the inner orpivot ends are attached to posts D D having pintles above and below, turning in the rims A A. The outer edges of the vanes. have hinged to them rods G G, each rod connecting the pair most nearly opposite each other, -as shown.

aronndbetween the rims and the posts B, and hori- Sides of oanvasor thin wood H may be extended c zon tal slots are cut through so as'to allow the rods G to play hack and forward.v

gFig. 2 will show more clearly the operation oi' my windmill, the wind being represented as coming from vthe direction oi' the arrow. i A v As the opened vanesybegin to move toward the wind in their revolution, the ypressure against theirn backs.-

will begin to'close them and openthe varies opposite, which are'counecied bythe rods G. v

As soon as these are pz'trtiallyopened by this means, the force oi' the wind will complete their extension and the cloningr of thefop'pcsite and returning vane. This occurs successively with each pair of vanes when they reach the proper posit-ion, so that there will be a constant force to drive the mill. i'

The lower rim A is mounted on arms I which extend to acentral hub and serve to support the mill. I

The'driving shaft J carries a pinion, K, atits lower end or at some convenient point, and from this such machinery as may he neededjs driven.

What. I claim, and desire -tb secure by Letters Patent, isg A horizontal windmilll having the Yanes C pivoted at one side, and operated bythe rods G connectingk the outer edges of each pair ot' opposite Valles so as to cause one to open and the other to close simultan--V` ueously, as herein described.

In witness whereof I have hereunto set my hand
